Advantages of HDCVI

TechPro Security recently announced they launched the sale of a brand new technology, a little something called HDCVI. Have you ever heard of HDCVI? Well if not I’ll break it down for you. First, HDCVI stands for High Definition Composite Video Interface. HDCVI is a video transmission technology that truly has the ability to open new and improved views to the security system world. This new technology is similar to almost every camera system out there in many different ways and on top of that it outperforms most. Having one of these systems might just be the way for you to go. Want the quality of IP for less? HDCVI is there. Want to be able to run coaxial cable farther than HDSDI? HDCVI is there. If that’s not enough for you, say you already have an existing analog system and want to try out some HDCVI cameras before buying an HDCVI DVR. The cameras have the ability to be run on an analog system as well. There is a purple and black wire attached to the pigtail of the camera that when twisted together allow the camera to be viewed on an analog DVR. Therefore, HDCVI is an optional solution for megapixel high definition application,

Both HDSDI and HDCVI systems have the ability to send and receive HD signal @720p. Although this may be true HDCVI has a great advantage in this category. For argument sake lets say HDSDI’s transmission distance will be 100 meters or close to 350’ give or take. Now, where HDCVI blows HDSDI out of the water, HDCVI’s transmission distance is about 500 meters or 1600’. I mean come on, that is a more than comparable difference. It’s 5 times the length you can place cameras. This not only broadens your options for camera placement, but also broadens your options for DVR placement for theft or damage prevention. Put it up against an IP system and HDCVI yields the same result. IP systems are great don’t get me wrong, the best quality but you have to pay for it. With IP the cameras run through a network which requires switches to connect all of the camera to the same network and then run a single cable back to the NVR. Seeing how IP systems interconnect show you how problem and delays can happen. If you wanted the NVR to be connected to the network for remote viewing you have to run a cable to the same switch and the cameras, which will place even more traffic. With HDCVI every camera uses a single cable per camera, which reaches back to the DVR which creates an isolation for each camera. So HDCVI is more reliable, same quality and more reasonably priced than an IP system.

HDCVI technology incorporates the use of both HDCVI cameras and HDCVI DVRs, and when put together as a system it’s nearly ingenious. The cameras options are limited in its launch phase but as the demand increases there will likely be varifocal lenses, PTZ (Pan Tilt Zoom) functionality, audio, and increased resolutions. The DVR acts just as any other DVR would running through coaxial cable, only being able to transmit a signal farther. Just like the cameras they are limited to amount of channels and storage space, but will eventually move to having higher storage (including expandable storage), more channels, and higher resolution capabilities. The HDCVI technology might also have a Hybrid addition where you can use HDCVI cameras along side IP so you can still enjoy the best of both worlds.

Another trick that gives HDCVI an advantage over Analog and HDSDI is the ability to not only receive signals but also to send creating a two-way transmission. To further understand multiple signal transmission over just one cable, both audio signal and dual-way data communication are embedded in what is referred to as a blanking zone. The blanking zone, in simpler terms, enhances the synchronization with video signal. The forward and reverse data channels composite in the frame blanking zone, grasping a two-way end-to-end transmission. In simpler terms the technology allows you to access the OSD controller from the DVR. This allows you to view a camera and operate functions within that camera such as, camera focus, Pan Tilt Zoom (PTZ) control, and also real-time alarm etc., all from the DVR. Also, the forward outputting data supports high transmission baud rate as the sending time and the electric signal baud rate are predictable. While that’s going on, the receiving end is of high performance. Opposite to that, the reverse outputting data supports lower baud rate due to its low signal frequency and limited data, which is affected by the impedance matching. Although, the reverse channel could restore electric signal during long-distance transmission to some degree.

The cost factor for HDCVI is considerably less than other the other technologies such as HDSDI and IP systems. With HDSDI You get the same quality but pay up to 3-4 times more than a comparable HDCVI. The reason for this is because HDSDI technology cost a lot to manufacture. IP technology has dropped in price tremendously over the few years it has been out, but is still expensive compared HDCVI. HDCVI also has the advantage over IP because if you have an existing analog system you can still take advantage of the existing wire, which will drive down the price. Also using the existing wire you have more capabilities than you would have with an analog without having to run additional cable allowing you to put PTZ’s or audio in places you want.
